119

141

100

129

✅ Correct Option: 4

A prime number is a number greater than 1 that can only be divided by 1 and itself. Note that 1 is not a prime number.

The first 10 prime numbers are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29

The sum of these prime numbers:

$2 + 3 = 5$

$5 + 5 = 10$

$10 + 7 = 17$

$17 + 11 = 28$

$28 + 13 = 41$

$41 + 17 = 58$

$58 + 19 = 77$

$77 + 23 = 100$

$100 + 29 = 129$

Therefore, the sum of the first 10 prime numbers is $129$ .
